I'm going to billet hubs on my early offset 86 951. The hub I have are made to fit 87+ spindles, so I want to change out the spindles.

A few questions before I start:

1. Will 87+ spindles and hubs fit an 86 car without affecting the offset? I still need to be able to run my Fuchs on this car.

2. Are all 87+ spindles the same or will I need to source a turbo set?

3. Will I need to change out the steering arms?

4. Does anyone have some for sale?

Cheers, Mike

I run late hubs/spindles/rotors/calipers but retained early control arms and tierods. I still have "early offset" but needed camber plates to get a decent amount of negative camber back. Prob would be ok without camber plates for a pure street car.

I am planning on going full late offset just havent bought the late manual tie rods yet...maybe later this year.

I'm also a tie-rod set away from the late offset conversion.

Thx, all my cars are 86, so I have nothing to compare.

So Just to confirm - I will need late turbo rotors & calipers too as well as the spindles and hubs or will the 86 turbo rotors and calipers work?

You will just need the late rotors, calipers are the same. You will also need camber plates.

SamGrant951

Yeah the reason I mentioned that I was running late calipers/rotors as I have big reds, sorry to confuse!

I have a set of camber plates so GTG there. Any difference between late 951 and late 944na spindles?

There is no difference between late NA and late Turbo spindles.
Did you ever do this swap/mod?
I found another set of Early struts to machine the adapter needed to get Late spindles on the Early rebuildable struts without needing camber plates. There is a 4 degree difference and 5mm bolt spreadwith that will be dealt with. I have decided to put on the late spindles, late control arm offset on Early struts so I can bypass the 1" spacer for the Turbo twist II wheels on my 85.5 car.

Why are you keeping the early struts then? Couldn't you swap the struts and be done with it?

xschop

The Early struts are rebuildable by unscrewing the cap, installing the new strut and screwing it back on.

Yes it's done. I now have early offset (86) control arms with late offset (87+) spindles and hubs. The hubs are the Racers Edge billet type which are only made for the 87+ spindles. I fitted late Ground Control coil-overs so I did not have to do anything at the flange/spindle. So the car is still an early offset and can run all the early wheels (Fuchs etc). The mod does change the camber ability of the car, you really need to fit camber plates (which I did) to give you more adjustment for a track car but it has plenty of adjustment for a street alignment.

Advantages:
1. Uses stronger/thicker 87+ spindles and hubs
2. Can upgrade to billet hubs.
3. Can keep rebuildable struts (after modding the flange plate holes and fitting a spacer for the spindle).
4. Can still run early wheels.
5. Keeps the lower unsprung weight of the early offset cars.

Disadvantages:
1. does not allow enough camber for track cars without camber plates.

Hope this helps - Mike

"you really need to fit camber plates"

"Disadvantages:
1. does not allow enough camber for track cars without camber plates."

The machined mounting adapter I made reverses the 4 degrees from doing the swap and fixes this problem. The camber will still be adjusted +- at the spindle attachment point. No need for camber plates.

When I am finished with my custom 2nd Gen control arms for my project, I will be doing billet hubs for Early cars machined with larger outter axle bearings. Stock ones hold 5500 lbs static and the new ones hold 8800 static lbs and can handle alot more heat. I am also going to machine the billet hubs to accept the large 318mm Boxster S rotors from the get go.

MAGK944

Good work xschop, I like the idea of billet hubs for the early offset's, especially with the larger outer bearings and Boxter S rotors. The coilover struts I got from GC came complete with camber plates, but I would like to see pictures of the mounting adapter you made.

I just won a complete set of Early struts from da bay and will mod them up shortly. I also have LATE NA and a set of "S" spindles to go on them (They are exactly the same). The M030 spindles are different only in the Radial mounted calipers and they have 3mm extra spindle shaft length. I just recently read about the 3mm difference here somewhere. So basically any late NA spindle with Boxster S rotors and Lexus 4-pots will outperform M030 stuff
Why Porsche ever went to the Late style Strut is beyond me other than at the time they could ensure you had to buy new ones for the late cars.
